To all whom it may concern:

Be it known that 1, WILLIAM Ems'rus WILLIAMs, a citizen of the United States, a resident of Wilmette, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Disk-Wheel Hub Fastenings, of which the following is a specification.

The object of my invention is to furnish a very cheap and secure fastening for the disk of a disk wheel to its hub.

Reference will be had to the accompanying drawings in which Figure 1 is a front elevation of the main portion of my preferred form of the wheel.

Figure 2 is a side sectional view..

Figure 3 is a rear elevation of a portion of a disk surrounding the hub of the disk form. shown in Figures 1 and 2.

Figure 4 is' a front elevationof the hub alone.

Figure 5 is a rear elevation of the hub clamping flange 12. 7

Figures 3, 4, and 5 are special to the structure shown in Figures 1 and 2.

Figure 6 is a front elevation of a modifled form of the wheel the difference between the structures of Figure 1 and Figure 6 relating to co-acting'hub-clamping features.

Figure 7 is a vertical sectional elevation of the wheel shown in Figure 6.

Figure 8 is a sectionalview on line 8--8 of Figure 7.

Figure 9 is a perspective view of a portion of the disk alone as used in Figures 1 and 2.

Figure 10 is a perspective view of the disk as shown in Figures 6 and 7.

In the drawing 1 indicates the hub of an automobile wheel here shown asthe rear he wheel shown 1n Figures 1 and 2 is what is known as a convex typeof disk while that shown in Figures 6 and 7 is for a concave type of disk, hoyvever either type of disk may be used with either fastening.

In Figures 1 and 2 the integral hub flange 4 is rovided with a fla'ngehaving a ruflie rufiied inclined projecting flange 8 .on the hub aperture of the disk 9. The disk 9 is secured to the rim 3 through the medium of a horizontal flange 10 and rivets 11, but may be seated as desired in any suitable manner in connection with the rim 3.

The ruffled flange 8 is held in engagement flange 4 and flange 5 of the brake drum and are secured in the rear by nuts 19. A flange on the bolts 17 permits the bolts to stay in place and clamp the brake drum 2 to the flange 4 of the hub at intervals when the nuts 16 are removed for the purpose of. de-

mounting the disk from the hub in tire changes as is well understood.

The rufliedFflange on the disk seated in the hub as described makes a secure fastening for the parts and a cheap one to make.

In Figures 6 and 7 the integral hub flange is indicated by 21 to which the web 22 of the brake drum is secured by a series of bolts 23.

This hub flange 21 is provided with a ruflied outwardly extending flange 24 provided with reinforcing pads 25 through which there passes the bolts 23.

The disk which forms the web of the wheel in Figures 6, 7, and 8 is provided with an inclined ruflied flange 26 which is seated onthe rufied flange 24 of the hub. The hub clamping flange in the structure shown in Figures 6 and 7 is indicated by 27 and is seated on the hub barrel 1 with a small flange 28 and this flange 27 has a ruffled flange 29 which is seated on the rufiied flange 26 of the disk. The bolts 23 are provided )with shoulders 30 that allow the nuts 31 to clamp the brake drum and integral flange 21 of The hub together. Demounting nuts 32 also on the bolts 23 serve to clamp in a demountable fashion clamping flange 27 and thus to secure demountable fastening for the disk and hub.

wheel extends from the ruflied hub flange 26 p d through the region 33 into the swell 34 and or fluted tapering seat 7 adapted to fit the merged forwardly into the felloe face 36 and from this turned over into an inclined flange 37 and this turned into the marginal flange 38 and thus through the flanges 37 and 38 the disk is connected to the rim 3.

A series of clamping bolts 39 having nuts 40 serve to secure a member 41 in such manner that its margin 42 clamps the quick detachable rim 3 to its seat 37 38 on the disk.

In Figures 9 and 10 the disks'shown in Figures 1 and 2 and Figures 6 and 7 are associated together the difference being that the concave disk may be said to have a convex ruifled flange and the convex disk to have concave rufl'led flange. In either case the method of holding the disk to the hub is through the medium of a ruffled flange on the disk around the hub barrel connection.

The ruflled flange on the disk makes a cheap and yet a very ,secure fastening for a disk of any, thickness when seated on a hub flange by any suitablemeans of holding the disk and the hub together.

What I claim is 1. In a device of the class described, a disk forming the web of the wheel and united to the rim by a flange turned over on the margin of the disk on to which the rim is seated and a flange turned over in ruffled form around the hub aperture in combination with a hub having a surface adapted to seat on the ruflied flange of thedisk and a clamping flange bearing against the disk and adapted to press the same into engagement with the hub in a manner that the ruffled flange of the disk is made to fit snugly into the ruflled seat on the hub.

2. In a wheel of the class described,a disk forming the web of the wheel and provided with an aperture around the hub zone and said aperture having a ruffled flange turned out from the metal of the disk in an inclined position in combination with the hub having an. inclined bearing surface adapted to engage the said ruflied flange of the said disk a clamping ring mounted over the hub barrel and adapted, to clamp the disk in relation vided with a rufiled flanged aperture around the hub connection, in combination with externally convex, internally concave connections of the hub members adapted to fit, respectively, the internal and external faces of the ruflied flange on the disk.

4. In a device of the class described, a disk having a ruflied flange turned around a hub aperture, ahub having the flange approximating the shape of the ruflled flange on the disk and a clamping flange for clamping the said hub and disk together by means of a series of bolts passing through the hub flange and the clamping flange.

5. In a device of the class described, a disk having a ruffled flange around a hub aperture, a hub provided with a flange approximating the shape of the ruflled flange on the disk, a clamping flange for clamping the disk to the hub flange and having a bearing surface adapted to engage the ruffled flange of the disk and a series of bolts for clamping the clamping flange and hub flange together.

6. In a device of the class described, a disk having a ruflied flange around a hub aperture, a hub with a flange having a surface approximating the ruflled flange on the disk, a clamping flange adapted to clamp the disk to the hub flange through the medium of bolts passing through the hub flange and clamping flange and said clamping flange gaging a wedge fit in contact with the said Si ed at Chicago, in the county of Cook and tate of Illinois, this 21st day of December, 1922.
